For the second time, we have co-organized the Schuman Congress. This year edition was devoted to Schuman’s principle of solidarity. Students from various faculties presented their essays and all participants joined very interesting discussion. One of the discussion moderators was president of PL-Student-NL, Emilia Zalewska. Our special thanks to the guests from the Polish Embassy in the Hague, mr. dr Piotr Perczyński and mr. dr Piotr Kobza.
